COPYHOLDECR.

Application filed. September 24, 1927.` Serial No. 221,635.

The present invention relates to type- :writer copy holders,and moreparticularly to an improved copy holder adapted for use with allstandard makes of typewriters and adapted to be collapsed so as to litin any one of the common makes of typewriter desks.

Although there are .a great many types 'of typewriter copy holders onthemarket at the present time, still there is no practical. holderavailable to thev public that can be collapsed into a desk along withthe typewriter. In general, the holders that are most universally usedare cumbersome, unweildy and unhandy. Many of the holders are notcapable of receiving diferent..widths of paper. Moreover, a greatmajority of the holders are not capable of making the regular one, twoand three spacings on the copy to conform with the spacings used on thetypewriter in making the copy.

An object of the presentl invention is to provide a copy holder capableof use with any standard make of typewriter.

Another object ofthe' present invention is 'to provide a collapsiblecopy holder-adapted to be collapsed into any of the standard makes of-typewriter desks.

Another object of my invention is to provide a copy holder having arevolvable cylinder paper feeder that is capable of accommodating from 6to 20 width paper and above.

Still another object of the invention is the provision of a copy holderincluding arevolvable cylinder wherein the copy is suspended in aperpendicularposition from the cylinder; all of theJ copy being open tovision.

A further object of the invention is to provide a perpendicular copyholderthat will collapse and'expand readily and without screwing andunscrewinghand screws, or a great deal of trouble and time.

A still further object of my invention is the provision of a copy holdercapable of making a regular one, two and three spacings on the copysimilar to the spacings used on the typewriter in making the copy.

Other objects and advant es of myinvention will more. fully appear romthe following detailed description taken in connection with theaccompanying drawings, which illustrate a single embodiment thereof, andin which:

y. In the drawings:

Like reference characters designate similar parts throughout the severalviews.

The reference character 10 designates generally the base of the copyholder and comprises a channeled sheetmetal construction, as is clearlyevident from Figure 3. This base includes a pair of parallel laterallyextending arms 11 and 12 and a connecting portion 13 disposed betweenthe arms. Secured to the connecting portion 13 are a pair of verticalupright rods 14-14. These rods are spaced from each other and areparallel to each other. It is upon these rods, as 'will become moreapparent hereinafter, that the upper frame portion ofthe copy holder isadapted to slide.

The upper frameJ of the copy holder in cludes a pair of spaced vertlcalsupport members 1515, each of which includes an inwardly turned ear 16having an opening` 17 through which a rod 14 extends. It will thus beevident that the two support members 15-15 are slidably mounted upon therods 111-14. The upper end of each of the support members I5 has formedintegral with it a laterally extending arm 18 (Figure 4). A spacing rod19 rigidl connects the two arms 18-18 together. These two arms 18-18rotatably carry a paper feed cylinder 20 the platen on "a typewriter.This platen includes a shaft 21, the ends of which are journalled in thetwo spaced arms 18-18 of the frame members 15-15. Also the cylinder 20includes a rub ber covering 22 in order to prevent slippage between thepaper on the cylinder and the cylinder.

Associated with each support rod 14 is a locking member 24 having formedintegral with its lower end an ear 25 secured to the adjacent supportmember 15. Since each of the locking members 24lis identical inconstruction to the other locking member, it is thought that adescription of one will sufce for both. Also secured to the ear 25 ofthe locking member isa pin 26 which carries a sniall leaf spring 27having its upper end in engagement with the vertical or resilientportion 28 of the locking member (Figure 4). Formed integrally with theupper end of the resilient portion 28 is a lateral arm 29 -havingsecured toits underside a stop block 30. 'llhe under surface of theblock 30. as shown in Figure 4, is adapted to normally contact the upperend of the Vassociated support rod 14. One side of the block 30 abuts aleg 31 of an angular piece 32 secured to the associated support member.insures that the stop block 30 will be properly aligned with the upperend of the support rod 14.

In order to permit the two support or frame members 15 to be moveddownwardly upon the support rods 14, it is necessary that the lockingmembers 24 be each moved out of the path of the upper end of theassociated rod 14. n other words, each locking member must be moved to adisengaged position such as that indicated by dotted lines in Fig- .lure 4. I shall now describe the manually operable release mechanism formoving these locking members 24 to their disengaged positions.

Extending transversely of the copy holder and disposed substantiallyparallel to the base 10 is a release rod 35 having its ends roi tat-ablymounted in the two spaced frame members 15-15. Each end of this rod 35is two support rods 14-14. the same may be accomplished by merelyturning the handle 37 so as to bring each of the U-shaped projections 36into a dotted position such as that shown in Figure 4. Each projection36 in assuming this horizontal position strikes the resilient verticalleg or portion 28 of the associated locking member 24 and moves theupper end of the locking member laterally away from the rod 14.Obviously this movement This angular piece 32 of each of the lockingmembers 24 results in the compression of the associated leaf spring 27.It, therefore, follows that when the handle 37 is returned to its normalposition, the

`leaf springs 27 will become effective to urgev the locking members 24back to their engaged positions. When the locking members 24 are intheirdisengaged positions, the upper frame members 15-15 and thecylinder 20 move downwardly due to gravityA to the dotted position shownin Figure 1. The upper frame structure including the' frame members 15may be returned to their operative position by raising the same asuflicient extent to permit return of the locking members 24 to\ engagedpositions.

lt shall now proceed to describe in detail the mechanism for indexingthe cylinder 20. Secured to one end of the shaft 21 of the cylinder 20is a ratchet wheel 40 disposed adjacent the outer surface of one of thearms 18, as shown in Figure 7. Secured to this arm 18 is a pin 41 whichsupports a leaf spring 42, the lower end 43 of which engages the teethof the ratchet wheel 40. 4The purpose of this leaf spring 42 is Vtoprevent the ratchet wheelV from being turned in a counter-clockwisedirection as viewed in Figure 6.

Positioned between the ratchet 40 and-the associated arm 18 is a plate44 loosely mounted upon the shaft 21. This plate has three smallopenings or holes 45, 46 and 47 cooperable with a ball 48 mounted in anopening 49 in the associated arm 18 (Figure V,7). One side of theopening 49, as best shown in Figure 7, is normally maintained closed bymeans of a leaf spring 50 secured by a screw 51 to the arm 18. This leafspring 50 serves to resiliently urge the ball 48 into cooperation withthe plate 44. The ball 48 is adapted to engage in any one of the threeholes 45, 46 and 47, depending upon the particular spacing required, aswill be more fully explained hereinafter. Formed integrally with theplate 44 is an offset laterally extending arm 52 adapted to be manuallyengaged to rotate the plate 44 upon the shaft 21. This offset arm 52. asbest shown in Figure 2. includes a handle 53 arranged away from theperiphery of the cylinder 20v where it is readily accessible. Formedintegrally with the plate 44 is a shoulder 54 adapted to engage a stoppin 55 secured to the associated arm '18 to plate 44 about the l58 isadapted to engage the teeth of' the ratchet wheel 40 to index thecylinder 20.

Formedintegrallywith the arm 58 is a laterally extending arm 63 which.has secured to its` free end one end of a spring 64. The other endvofthe spring 64 is secured to the spacing rod 60. The position of arm58 is determined by the positionof the pin 56 which is connected to thearm 52. Obviouslyv when the ball 50 is in the opening 45 in the plate 44the pin 56 will be disposed in its uppermost position thereby "enablingthe arm 58 upon an operation thereof to index the ratchet three teethcausing the cylinder to make whatis usually termed a triple space. Onthe other hand, when the ball 50 is in cooperation with the opening 46,the pin 56' will have beenmoved to its intermediate position whereby thearm 58 will be permitted to index the ratchet wheel two teeth, thuscausing the cylinder 20 to make a double space. Furthermore, when theplate 44 is -moved so as to bring the opening 47 into cooperation withthe ball 50, the arm 58 will be caused to index vthe ratchet v40 onetooth whereby the cylinder 20 will make a single space.

f The plate 44 has a projection 44 adapted upon the rotation of plate 44in a counterclockwise direction to move the end 43 of the leaf spring 42o ut of cooperation with the teeth of the ratchet wheel 40, whereby itis possible to rotate c linder 2O .any degree desired independent y ofvthe ratchetl teeth. The turning of the plate 44 in a counterclockwisedirection is accomplished by merely raising the arm 52 connectedthereto.- Thus, it will be evident that the leaf spring 42 may bedisconnected with facility from the ratchet wheel 40. v

It will, of course, be understood that the operation of the arm 58 isdependent upon the downward movement of the spacing rod 60. This rod 60extends downwardly alongp side one of the support members 15 and hasformed integral with it an oset portion having an elongated slot 66(Figure 2). Ex-

tending into the slot 66 is a pin 67 secured to 71 and 72 travel in theslots of the rod60 to guide the roel` in its vertical movement. Securedat one end to the upper end of the offset portion 65y is a return spring73, the upper end of which is secured to a p1n 74 secured to theadjacent support member 15. This spring functions after each Vdownwardmovement of the spacing rod 60jto return it and the associated parts totheir normal positions. The lower end of the vertical rod 68 ispivotally attached to one end of a lever 75 pivotally -strp 93 are aconnected between its ends to a lug 76 formed integrall with arm 12 ofthe baselO. The other en of the lever 75 is pivotally connected to oneend of an operatinglever 77. An intermedia-te portion of this operatinglever 77 is pivotally connected to a lug 78 also secured to arm 12 ofbase 10. The other end of the operating lever. 77 (Figure 3) is providedwith a linger portion'80 adapted to be engaged to operate the spacingrod 60. It will thus be evident that upon the depression of the fingerportion 80 of lever 77, the spacing rod 60 will be pulled downwardlycausing the v operation of arm 58 to turn the ratchet 40 whereby thecylinder 20 is indexed a predetermined degree.

I shall now proceed to describe lin detail the mechanism for holding the.paper to be copied in cooperation with the cylinder 20. Extendingtransversely of the base 10and secured at its ends to the arms 11 and 12of the base isa rod 81. Pivotally mounted upon this rod.81 (Figures 1and 4 is a verticallyv arm 83 is a vertical pin 85 secured at its'lowerend to the intermediate or connecting portion 13 of the base 10. Acollar 86 surrounds the pin 85 and is disposed between the bottom of thebase 10 and the arm 83 (Figure 4) This collar 86is normally engaged bythe under surface of the arm 83.l Also surrounding the pin 85 is laspring 87 which serves to at all times urge the arm 83 downwardly intocooperation with the collar 86. The upper end of the spring 87 abuts anadjusting nut 88 threaded upon the upperend of the pin 85.

Slidably mounted upon the upper end of the vertical member 82 is atubular block 90 to which is rigidly secured a pair of upward- 1yextending diagonal elements 91 and 92.

The upper ends of these two diagonal elef straight-edge or lineindicating strip 93 disposed in front of the periphery of the cylinder20. The top edgeof this strip is adapted to be disposed directly belowthe line which is being copied at any one time. Also secured to thestrip 93; are a pair of curved paper guides 94 andY 95 which extend overthe periphery of the cylinder 20. Fastened to an intermediate portion ofthe strip 93 is a handle 96 by means ofwhich the strip may be pulledlaterally away 'from the perlphery of the cylinder 20. Rotatably mountedin the pair of rollers 97 and 98 adapted to engage t or the surface of te paper extending over the .cylinder 20. The two guides 94 and 95 arereinforced by a connecting rod 99, as shown 1n -lFigure 1. Attention isdirected to the fact pin 101 secured to the upper end of the verticalmember 82. Fastened to one side of the block 90is a leaf spring 102having its lower end bent inwardly toward the member 82, as. indicatedat 103. rlhe bent end 103 of the leaf spring 102 is adapted to engage ina notch 104 in the member 82. Also secured to the leaf spring 103 is alateral extension or finger piece 104 adapted to be depressed in adirec- Y tion toward the block 90 whereby the bent end 103 of the leafspring 102 can be moved out of cooperation with the notch 104in themember K 82 to permit the block 90 sliding downwardly upon member 82. Inother words, by releasing the leaf spring 102 from cooperation with themember 82, the diagonal elements 91 and 92 and the straight-edge strip93 will gravitate to the dotted position shown in. Figure l.

At this time Iwish to direct attention to the fact that shaft 21 of thecylinder 20 also has secured to its end a knob 100 of the sameconstruction as the knob employed on the platen of the conventionaltypewriter. It will thus be obvious that the cylinder 20 may be-actuatedindependently of the spacing rod byv merely turning the knob 100.

The operation of my novel copy holder is believed to be evident from theforegoing detailed description and I shall therefore touch upon only themore important phases of the operation of the device. The device isdisposed in a position .in the rear of the typewriter and directly infront of the typist. 'Ihe paper to be copied is inserted between theroll 20 and the diagonal struts 91 and 92.

'Ihe rst line on the papersis brought into a position where it isdirectly above the strip 93. It will therefore be apparent that thepaper is suspended in a perpendicular posir tion from the indexingmechanism,namely, the cylinder 20. After the ,line has been copied bythe typist, the cylinder is ,indexed by merely depressing the fingerportion 80 of the lever whereupon the sheet is'moved upwardly a distancexed by the spacer. rIhe spacing made by the cylinder 20 depends upon theposition of the arm 52, as previously described. fter the Work hasl beencopied, the paper is Vremoved from the device and the device istelescoped. By telescoping I mean the lowering of the upper frame of thedevice upon the rods 14-14 to the dottedposition shown ingFigure 1. Itwill, of course, be evident that the straight-edge 93 and the diagonalelements 91 and 92 connected thereto are :tamara lowered independentlyof the frame members 15-15. I
